Abstract An ion beam transport system has been designed to transport a highly intense and bright beam extracted from the H − ion source. This new system will be installed at the new injection terminal for the TRIUMF’s 500 MeV H − cyclotron. The low energy part of the transport section (25 keV) in the injection terminal has been designed with magnetic optical elements in order to maintain space charge neutralization. The injection terminal includes a permanent magnet lens, magnetic steerers, a pulser, a beam dump, and a 300 kV acceleration column with electron and positive ion suppressor rings. Beam optics calculations have been performed, including space charge effects up to 1 mA. The simulation results of the beam optics design are presented in this paper.
